The Biochar Miracle
Carbon pirates bury black gold… so future generations will be richer. – John Rogers
Biochar is being promoted as the soil saving miracle of the century promising outrageously high yields of crops as well as removing carbon dioxide from the atmosphere. The first video ‘The Promise of Biochar’ explains what biochar is, how valuable it is and how the Amazonian Indians used it to enhance fertility of the soil and promote carbon sequestration.
200 year old Brazilian soil [Terra Preta] which has been treated in this way was found to be ultra fertile and bio-diverse even centuries later. Also shown is an in-field experiment comparing the vast increase in crop production through using biochar techniques versus slash/burn or mineral fertilizer methods.
The second 24 minute long video — ‘Making Biochar with Jolly Roger Ovens’, details John Rogers’ latest experiment in a 5-year quest to make top quality biochar. The piece opens with a demonstration of the finished product in action followed by step by step info on construction of the biochar generator.
